Jim S. and I have been working through why St.J Yard, admittedly small, gets jammed up.

One question we had was: "What is the number of cars that St.J is being asked to handle, over the course of a "day" ? "   To this end I have added to ProTrak some tracking of the number of cars being setoff and the number of cars being classified.  This tracking is for all "Yd" yards.

The data is added up over the course of the "day".  The data is re-zero'ed when the Daily Summary runs.

You can see this data, with the December 5th Update.  Look at your list of yards.   There has been a column for "capacity".  Now the two columns to the right show "Cars setoff" and "Cars classified".  The data in these columns is current to the current status of your railroad.

~~~

If you have any ideas on how this data might be improved please let me know.

Thanks,

              Jim

Jim,

TIME OUT !!!!   You teased us with your insight and subsequent SW changes wrt the status of in-coming and out-going cars at your St. J Yd.  Many of us have worked that yard during your fine ProTrak weekends, and yes it is a tough yard to work.  So would you please share what your new statistics told you and Jim S about St. J.   Say hello to Jim S for us all.

thanks

Joe

Greetings one and all ....

What was acomplished: we made up a 26 car train in 30 minutes.
How we did it (1): I ran the engine while JM acted as contuctor/switchman.
How we did it (2):

  • a track was selected to build the train
  • we pulled out a section of cars from a given track
  • as each car passed a "line in the sand" the car reporting marks were compared to the switch list
    • if the car was on the list it was shunted to the "building track"
    • if the car was not on the list, it was placed onto, for the lack of a better term, "rejected car track"

NOTE: we did not go up and down the various tracks looking for specific cars

What I learned from the exercise:

  • one must dedicate "A" track to build the train
  • one must understand what other tracks are avialable to them for sending rejected cars and for room to pull cars out, cut them, then move them to the building track.
  • track mounted uncouplers (magnets) are very nice to have
  • local/expert knowledge really helps thus making training and development of operators (conductors and engineers) critical parts in making the rr run - just as important as making sure track is in gage for example
  • read the switchlist - top to bottom as there is a lot of information that will help you to do a better job
  • I feel like I can handle most any yard ... it may take me a bit of time to figure out how to make it work but once I find a track to build onto I am able to execute the job

Hope this helps
Best

Hi Jim S.

I guess that presumes that the cars assigned to the train were correctly classified to the track you are pulling.  Or do you pull every track in the class yard until you find all the cars? In a big yard, that is quite a job.  When pressed for time, I guess you could simply report a few cars missing.

Hi John, when Bob B and I worked that yard, the problem was that there was too many destinations and outgoing trains to assign outgoing destinations to.   As cars arrived, we just placed them on whatever track was available. As we worked outgoing traffic, that is when, as Jim S explained, we would pull each track and setout any cars for the outbound train. We would then blocked the cars for the outgoing trains, which was necessary for dynamics.   It kept us very busy but it was quite enjoyable once we got the hang of it. Best , Andy

Jim S. noted:

Jim S. has been emphasizing! these two points to me.   I have been listening, and we have been trying to figure how to actually "convey local knowledge" and do the necessary training.   Is written material limited in effectiveness?   Jim has suggested a day's worth of hands-on training as the first day of the Weekend.

Essentially, while Jim was being a footboard yardmaster, I was a) conveying to him "local knowledge" and b) training him in fine nuances of running St.J. yard.

~~~

The same applies to the other yards, especially Baden.

Thoughts?

Interesting idea.  IN general Jim M should ALL of your yards be worked the way Jim S wrote about the other day?  Haven't heard any comments from Yardmaster specialist Howard G.  

Secondly - make the clinic on Yard Operations a feature when announcing your next weekend and use that to try to entice more users to come to a ProTrak weekend.

It all depends.  Like anything else different yards require different approaches.

For Jim's yard, the pull every track method is probably the best since there is not enough room to class everything  properly.

In Andy's Gresham yard, 99 percent of the time all the cars will be on one track.  There will be extras that need to be cut out.

I look forward to working with the new yard information
